The BWT AQA-PURA under-sink filter lets you rediscover the taste of tap water with a simple, economical, and eco-friendly solution that delivers purer water directly to your tap. Discreetly installed under the sink, it requires no modifications to your existing faucets. It treats all your cold kitchen water using an activated carbon cartridge that effectively removes unpleasant tastes and odors, chlorine, pesticides, and heavy metals, while also retaining some long-chain PFAS depending on usage conditions. Compact (less than 30 cm), it installs in under 30 minutes thanks to the complete kit included: filter head with bracket, protected filter cartridge, and 3/8" connection hose – without the need for drilling or faucet replacement. Its high filtration capacity, up to 10,000 liters or one year of use depending on the water, allows for easy replacement by unscrewing, offering a sustainable solution that reduces plastic waste and eliminates the need to buy bulky bottled water. Among its main advantages: tasty and odorless filtered water directly from the tap, total compatibility with standard taps, quick installation with minimal space requirements, one year of autonomy per cartridge, up to 400 Euros in annual savings depending on consumption, and a true ecological alternative to plastic bottles.
